Disentangling multi-spin dynamic correlations in the Heisenberg spin- chain
V. K . Bhartiya, U. Kumar, T. Kim +8
Higher-order correlations are essential for understanding exotic phases and uncovering universal aspects of quantum dynamics. While inelastic neutron scattering provides well-estab…
Magnetic excitations and absence of charge order in the van der Waals ferromagnet FeGeTe
V. K. Bhartiya, T. Kim, J. Li +12
Understanding the ground state of van der Waals (vdW) magnets is crucial for designing devices leveraging these platforms. Here, we investigate the magnetic excitations and charge…
Evidence of electronic states driving current-induced insulator-to-metal transition
V. K. Bhartiya, R. Hartmann, F. Forte +16
On demand current-driven insulator-to-metal transition (IMT) is pivotal for the next generation of energy-efficient and scalable microelectronics. IMT is a key phenomenon observed…
Dispersive dark excitons in van der Waals ferromagnet CrI3
W. He, J. Sears, F. Barantani +11
Spin-flip dark excitons are optical-dipole-forbidden quasiparticles with remarkable potential in optoelectronics, especially when they are realized within cleavable van der Waals m…
